lApplication filed August 7, 1920. Serial No. 401,955.

To all iff/2mn. -z't may concer/n Be it known that I, ANDREW S. CAIRN- caoss. a citizen of the United Stat-es, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful lcing-hiachine. of which the following is a specification. y l

My invention relates to icing machines of that class in which cakes and other pastry are coated with frosting. The pri-mary object is to provide a. machine of the class stated in which the operation of icing pastry is facilitated and. in which the drip and surplus icing material is returned to a supply tank where it can be used, thereby reducing waste. A. further object is to provide a. simple and inexpensive machine of the kind stated by the use of which hand labor is reduced to a minimum and sanitation is benefited.

ln the accompanying drawing forming part of this specification, Figure 1 is a side elevation of. my invention; Fig. 2 is a plan of one half of the pastry icing table structure, one only of the pastry racks being shown; Fig. 3 is a cential longitudinal vertical section of the table structure taken on the line 3-3 of Fig. 2; Fig. 4 is a plan of the icing receptacle, and Fig. 5 is an enlarged section taken on the line 5-5 of Fig. 2, showing the construction of a portion of the table structure.

My invent-ion employs a rack or icing table struc-ture A on i Thich the cakes or other to be frosted are placed, and an icing receptacle B in which the icing material in liquid condition to be used is placed and into which the surplus or waste icing material dripping from the cakes on the racks returns.V The rack table consists of a vertically disposed cylindrical casing 1() closed at its lower end by the disk plate 1l and supporting a downwardly sloping floor 12 below the upper portion of the casing forming a drip pan for the icing. The structure thus forms a hot water tank by which the drip pan is heated so that the icing caught by the pan will not harden and will flow downwardly over a projecting lip 13 through the opening 'ist in the casing and into the supply receptacle B. lVater is fed into the tank by the valved supply ductrl and may egress through the valved outlet 15. A steam coil 17 in the tank serves as one means by which to heat the water.

Arranged in the casing above the pan is a horizontally disposed revoluble rack frame composed of three evenly distributed intersecting beam members 20, 2l and 22,.

'mounted atI their ends on a circular angle vmember 23 and braced by the transverse `members 24 near the center of the frame.

ing the rim tightly over the upper side of thel angle member 27 and securingl rivets 29 or other suitable means through the angle member 27 and the adjacent sides of the rim (see Fig. The pivot 25 ournaled freely in a vertical sleeve 29 which is mounted at approximately the center of the casing to assist in guiding the carrier rollers concentrically within the casing. The rack frame C is thus free -to turn within the casing. Segmental shaped trays D made out of wire .grating or other open work material are placed in the open spaces of the rack frame. Cakes or other pastry articles are first immersed in the liquid icing in receptacle B and then placed on the trays D where they are allowed to drain untildrip ceases, whereupon each tray loaded with iced pastry articles is remo-ved from the rack frame to a drier. Bales 30 on the trays facilitate handling them. Y'Vhile the machine is being loaded with pastry articles or unloaded, the rack frame can be easily turnedby hand to facilitate their operation by an attendant. The drip from icingthe pastry articles upon the trays is caught by the sloping {ioor 12 and flows or passes b-ack into the receptacle B, th-us producing greater economy and sanitation. The receptacle B has a hot water chamber 31 for heating the icing material therein, the wat-er in said chamber being heated by a coil 32. A guard 33 above the opening acts as an anti-splasher for the icing. The table structure is supported by the frame 34 and the supply receptacle is supported by the frame structure 35.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l.' An icing machine,comprising, in combina-tion, a cylindrical casing having an opening in one side thereof, a bottom for ilo -saitl Casing', a downwardly sloping floor therein, extending at its lower extremity through Said opening, said Casing, bottom antl floor forming a chamber for a heating` medium, a central support passing through the floor and Secured at ite lower en l to eaicl bottom. a trame revolu1 said Support, an annulus Within the casing; having an upright 'flange turned inwartl at its lower edge to form a horizontal trael: member` the ripper eflge of saifl easing being turnetlL downward over the Hangt-x anal attaobetl thereto to strengthen thenpoer margin of the casino; antl secure the annnlns in place, antitriotion elements` between the frame and track member `tor Supporting' the onter margin of the latter andl severally removable trays of open work material car rietl by Said iframe.

An ieiirg` maehine. Comprising', in oombinatioii a cylindrical casing' having' an opening' in one sitle tlin'eof, a bottom for saifl casing', a i'loor in said casing sloging ilownnf'arilly toward Said opening', said oasing` bottom ancl floor forming' a Chamber for a heating medium, a. central Support in the easing', a .trame revolnbly Centered on Saifl Support, an annulue within the caeing having an upright flange turned innf'artl at its lower etlg'e to form a horizontal track member, the upper edge ot saitl casing being;` turnefl downward over the llange and attached thereto to strengthen the upper margin of the casing' anal Secure the annulus in place, antiiiriction elements between the trame and trank member for Supporting the outer margin ot the latter and severally :iily centered on l removable trays of open work material carrietl by Said frame.

3. An icing machine, comprising, in oombination, a cylindrical, sheet-metal easing having' an opening in one eide thereof, ay .sheet-metal bottom for saicl'casing, a sheetmetal floor in said casing;` sloping' clownwaii'tlly toward Said opening', said Casing, bottom and Vfloor :toi-ming` a Chamber for a heating medium, a central support passing' through and braoetl by the floor and secured at its lower end upon Said bottom, a frame 'revolubly Centered on Said support, a circular trswllwithin the casing adapt-ed to Stiften the Same. antitrietion elements between the Ytrame and track for supporting the outer margin of the latter and severally removable rays of open work material carried by eaiil l" 'ame Jr. in icing' machine.` compreing, in oombiation` a Cylindrical casing' having an opening' in one sicle thereof, bottom for eaitl easing, a Afloor in Said easing sloping' downwardly toward saitlL opening', Said oasing', bottom and loor forming' a chamber for a heatingV medium, a` Central support passing through the floor and Secured at itel lower entl to said bottom, a frame revolubly eenteretl on Said support, a Circular track Within the casing, antifriotion elements between the frame and traelc for Supporting' the outer margin of the latter and severally removable trays ot open work material. oarriefl by Said frame.

ln testimony whereof I have signed my name to this specification.
